Ubuntu 23.10, codenamed "Mantic Minotaur", is here. This release
continues Ubuntu's proud tradition of integrating the latest and
greatest open-source technologies into a high-quality, easy-to-use
Linux distribution. The team has been hard at work through this cycle,
partnering with the community and our partners, to introduce new
features and fix bugs.

Security takes center stage in this release with experimental support
for TPM-backed full disk encryption landing on Ubuntu Desktop. Based
on the same architecture as Ubuntu Core, encryption keys are stored in
the Trusted Platform Module and only released by authenticated boot
software to protect against device tampering.

PPAs are now added as deb822-formatted .sources files where keys are
directly embedded into the file’s signed-by field to create a 1:1
mapping between the PPA and its key.

Ubuntu Desktop 23.10 is based on GNOME 45 and sports a brand new App
Center built in Flutter. This delivers a fast, intuitive way to manage
both snap and deb packages on your machine and lays the groundwork for
a richer store experience using snap metadata going forward. This
release also sees the return of ZFS guided install, and a change of
the default install flow to prefer a streamlined set of default
packages.

Ubuntu administrators will benefit from the inclusion of Netplan as
the default backend for storing NetworkManager settings, unifying the
Server and Desktop networking experience. Fleet management has also
been improved with a new `pro enable Landscape` quickstart enrollment
feature and the inclusion of certificate auto-enrollment policies for
Active Directory as part of ADsys.

Ubuntu 23.10 delivers the latest toolchains and runtimes for Python,
Java, Go, C, C++, Rust, and .NET. This release also includes the
latest version of `docker.io` and the addition of both
`docker-buildx` and `docker-compose-v2` to support Docker developers
on Ubuntu.

Finally, we are excited to announce that Ubuntu 23.10 will support the
latest Raspberry Pi 5 upon its release later this year.

The newest Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon,
Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, Ubuntu Unity, and Xubuntu
are also being released today. More details can be found for these at
their individual release notes under the Official Flavours section:

Maintenance updates will be provided for 9 months for all flavours
releasing with 23.10.
